DT-26, 32.768kHz OSCILLATION CIRCUIT EVALUATION（KDS）
1. CRYSTAL UNIT SPECIFICATIONS AND CIRCUIT CONDITIONS
<Crystal Unit Specifications>
KDS P/N: 1TD125DHNS004
Load Capacitance: 12.5pF
ESR Specified Value: 40kΩ max.
Room Temp. Deviation: /-20ppm
Turnover Temperature: 25±5°C
Parabolic Curvature Constant: -0.04ppm/°C2 max
<Circuit Condition>
Negative Resistance: 5 times more than ESR specified value
Drive Level: 2μW max.
2. CONCLUSION
With the current circuit constants, the circuit satisfies the circuit conditions, so that there would be no
problem with oscillation.
[Note]
These analysis results are from only the circuit board we received this time, and we are not
considering the tolerance or deviation of the mass production. So, we recommend confirming more
circuit boards for the mass production board at your side.
